Scientists “wish to resign as co-authors:” Quantum dot paper retracted

with 21 comments

chemcommChemical Communications has retracted a 2015 article by a group of researchers in China over concerns about fabricated data and an incredible shrinking list of authors.

The paper, “N, S co-doped graphene quantum dots from a single source precursor used for photodynamic cancer therapy under two-photon excitation,” was ostensibly written by nine researchers at the Collaborative Innovation Center for Marine Biomass Fiber, Materials and Textiles of Shandong Province, the Shandong Sino-Japanese Center for Collaborative Research of Carbon Nanomaterials, Laboratory of Fiber Materials and Modern Textiles, the Growing Base for State Key Laboratory at the  College of Chemical Science and Engineering at Qingdao University, and Mayo Clinic, in Rochester, Minn.

Bielawski and Wiggins retraction count grows to six

with 3 comments

chemical scienceA group of chemists whose work was investigated by the University of Texas-Austin has had another paper retracted, this one of a Chemical Science study previously subjected to an Expression of Concern.

That makes six retractions for Christopher Bielawski and Kelly Wiggins.

Here’s the notice for “Homonuclear bond activation using a stable N,N′-diamidocarbene”, signed by all three authors of the paper: Read the rest of this entry »

Chemists Bielawski and Wiggins up to eight expressions of concern, one retraction

with 7 comments

Christopher Bielawski

Two researchers who already had three expressions of concern under their belts have five more, plus a retraction.

Kelly Wiggins and Christopher Bielawski share authorship on all the papers in question. After the first set of EoCs, Bielawski, at the time a PI at UT Austin, told Chemistry and Engineering News that a “former lab member” had admitted to faking the data. The recent retraction indicates that University of Texas at Austin’s Office of Research Integrity formally investigated the lab, and determined that Bielawski was telling the truth about a former lab member being to blame.

Bielawski has since taken a post at Ulsan National Institute of Science and Technology in South Korea. He told us that move was unrelated to anything that happened at UT Austin, but declined to answer other questions. Wiggins got a postdoc at the University of Illinois, which an Illinois spokesperson confirmed lasted from July 1 2013 to January 22 2014; we’re waiting to hear back on our question about whether her departure had anything to do with misconduct.

Second expression of concern appears for chemistry group under institutional review

with 21 comments

chemsciThe journal Chemical Science has issued an expression of concern over a 2012 article by a pair of Texas researchers whose “unclick reaction” work has been under scrutiny by their institution.

The article, “Homonuclear bond activation using a stable N,N-diamidocarbene,” was written by Kelly M. Wiggins and Christopher W. Bielawski, of UT Austin. It’s the second EoC that we know of for a paper by Wiggins and Bielawski. We covered a previous one, from Science, that appeared in June.

Authors retract two spectroscopy papers when follow-up results don’t match

with one comment

analytical methodsThe authors of two spectroscopy papers in Royal Society of Chemistry journals have retracted them.

Here’s the notice for “Determination of silk fibroin secondary structure by terahertz time domain spectroscopy” (free, but requires sign-in) in Analytical Methods, which is almost identical to this notice in Analyst: Read the rest of this entry »

Expression of Concern tarnishes copper oxide paper

with 21 comments

jmcacoverArticles, like lawn furniture, aren’t supposed to rust after just two months. But the Journal of Materials Chemistry A has issued an Expression of Concern for a February 2014 paper by a group of chemists from India over possible problems with several figures in the article.

The paper, “Hierarchically macro/mesostructured porous copper oxide: Facile synthesis, Characterization, Catalytic performance and Electrochemical study of mesoporous copper oxide monoliths,” was written by Gowhar Ahmad Naikoo, of the department of chemistry at Dr. Hari Singh Gour Central University, in Sagar, and two colleagues. It purported to find that:

Royal Society of Chemistry apologizes for unclear retraction notice

with 3 comments

jaasLast week, we reported on a retraction in the Journal of Analytical Atomic Spectrometry that left us a bit puzzled. The notice referred to a problem with “the way the data was presented,” but the authors told us this was just an error picked up in proofreading, somehow after the paper had been published online.

We now have much more of the story. The Royal Society of Chemistry’s May Copsey, who edits the journal, tells Retraction Watch: Read the rest of this entry »

Chemistry article retracted “due to the way data was presented”
